I reread all what I've written several times, I have to confess that it wasn't that clear at the begining. But I didn't mean to do that. It's really a huge misunderstanding because my limited level of English.
I don't want to continue to involve more people in this debate.
I just want put an end point to it.
I apologize, ok?
I will be more careful to express my thoughts next time.
Thx for some of you who understand me, I appreciate that.
But hope it's the end of debate, no matter whether you are in the pros or cons.
It is not an ethical issue. It is a just misunderstanding. In chinese, if we say "free of charge", it simply means without paying money. But I never noticed that we can't use the corresponding word to express the same meaning.
I don't want to deceive you, so I replied the arguments, to correct the misunderstanding.
I am not a linguist, English is not my mother language.
I tried several times to make it clearer, better.
But don't use the word"deceive", It's just sooooo offensive.
